Elfi #2, our more "educated" Elfi. He is a full four channel Elfi, with very effective ailerons (wish they were strip versus barn door type ailerons) that allow for nice tight aileron rolls (will some rudder coordination). Elfi #2 has traveled more than his siblings, to several states and also to Canada. PJS brushless motor now installed, running on a TP 3S 2000 mAh LiPo pack. He can scoot when necessary.
